My Dd, age 6, has always had ezema off & on behind her knees, it just seems to be getting worse recently, and spreading up her legs. I try crams for the homeopathic chemist, that have done bugger all really, if it gets really bad I put some hydrocortisone cream on it. Is it worth getting her tested for allergies? What kind of basic moisturiser is good to put on when it's not too bad? Any hints appreciated...
